Item 38 (Sponge)

38. A sponge is asymmetrical. Well this one comes from the kitchen sink rather than the Ocean floor, but I hope it still works.
Asymmetrical- When animal lacks consistant pattern of structure.
Radial Symmetry- Parts of animal are organized around in a circle around an axis.
Bilateral Symmetry- When there are two similar halves on either side of a central plane of the animal..
